Lip of box must be 34" above finished floor.
Maximum distance to trap weir is 48".
You cannot drill the 2"x4" stud to the left or right. Doesn't matter if it's doubled or non-load bearing.
Have to be x pipe diameters from the trap outlet to your T connection to avoid "crown venting".
You have to connect from the trap to a 3"x2" T or immediately convert from a 2" to 3" with a pipe increaser in the vertical.

Not that hard to breach the 48" threshold when the trap is below the floor, fitting dimensions, and joist heights.

It's all B.S. anyway.

I'm glad we don't follow the 2009 Version.

1/4"..... wow, did he break out a level and check each and every horizontal run for slope and make sure you were exact in slope and not a 1/16" off... that inspector needs to get off his high horse. That's complete bull crap and I'm not even a plumber. Almost all inspectors I have dealt with would be forgiving of a quarter inch... amazing.

About 25 years ago I was getting a final manometer inspection on a 13 unit condo with 26 bathrooms, 13 kitchens and 13 laundries all in one shot. Making sure over 100 traps are all filled and didn't accidentally get pulled because someone ran something was a pain. The inspector was the heating inspector who was filling in for the plumbing inspector who was on vacation. All this guy knew to do was to look for stray water, a caulked toilet base, and that the manometer held. He sat there for 15 minutes watching the manometer. (Really) and said it went down a little so it didn't pass. I informed him the test was just fine and that Bill (the real plumbing inspector) would pass it. So I would wait for a retest. He suggested we try looking at the manometer again. Amazingly it was OK that time. He really was a decent guy he just didn't know any better.

1/4" ?!? Jeez, thats a bit of excessive code enforcement. My inspectors aren't too bad except for 1 but compared to your guys he's easy. Sometimes my inspectors won't bother going to the job site if its something small like a shower valve and drain...lol. Had one come out the other week to look at a 300' run of 1-1/2" galvy lp gas pipe in the ground. He barely looked at the pipe, only enough to see it was wrapped and just glanced at the gauge...
